COMPOSITION FOR SOFTENING PRINTERS INK.

SPECIFICATION forming part of Letters Patent No. 369,969, dated September 13, 1887.

Application filed November 12, 1885. Serial No. 182,555. (Specimens.l

To all whom it may concern:

Be it known that I, GEORGE M. STANCE- FIELD, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful composition of matter to be used for the softeuing of printers ink, whether in bulk or upon the rollers of the press, and to prevent gumming and for softening old and stiff ink to any consistence required, of which composition the following is a specification.

My composition consists of the following ingredients combined in the proportions stated, viz: kerosene-oil, one gallon; sulphuric ether, one pint; essential oil of Sassafras, two ounces; essential oil of cloves, two ounces. These ingredients are to be thoroughly mingled by agitation. In using the above-named composition a small quantity of this composition is poured upon the stiff and dry-ink, and with a spatula or stick it is mixed into the ink, which soon becomes soft and liquid and free from lumps, or, applied upon the rollers of the press, cuts any old stiff ink thereon instantly and I enables the pressman to work his press at once without delay, and as this compound will not gum or harden, even in the coldest Weather, the press may be run without the necessity of warming the disks or forms by lamps or stoves, as is now necessary in cold climates. The use of this compound also prevents the sticking of the rollers in hot or damp weather. This composition does not dry, and so keeps the rollers soft and elastic and dispenses with the necessity of Washing the rollers for each new job.

This compound never changes by age, does not thicken or freeze at any temperature, and no matter how old the compound may be it is always the same.

I am aware that printers varnish and other compounds have been used for softening inks; but the practical result in the use of all the other compounds is that in a short time the compound becomes useless by hardening and growing sticky.

I am not aware that the ingredients of my combination in the proportions stated have been used prior to my invention thereof.

Vhat I claim, therefore, and desire to secure by Letters Patent of the United States, 1s

The herein-described composition of matter to be used for softening or cutting printers ink, either in bulk or on the rollers of the press, the same consisting of kerosene-oil, sulphuric ether, essential oil ofsassafras, and essential oil of cloves, in the proportions and for the use as specified.
